Chester A. Arthur Is the Most Forgotten President in U.S. History, According to Science

The third Monday of February, which many Americans know as Presidents’ Day, is supposed to be a time to remember George Washington’s Feb. 22 birthday. And few would argue that the first U.S. president doesn’t deserve to be remembered; likewise for Abraham Lincoln, whose Feb. 12 birthday is also remembered by many on the same day.

But, while Presidents’ Day may be well and good in terms of historical recognition, Washington and Lincoln hardly need a special day to stay uppermost in Americans’ memories.

For other presidents, the matter of memorability is quite a different story, two recent studies have shown.
